Custom guitar amp build
Built this custom one off guitar amplifier for a customer in the US. He had a bunch of very specific requests for this build that started out as a reissue Fender.
The ONLY parts that remained were the steel chassis and the timber cabinet...and knobs!
I designed two very different input channels based on his description and needs. The transformers were replaced with custom spec units as one of his requests was the desire to use ANY output tube from the little 6V6 through to big daddy KT88, hence the external bias test and set points on the back. The output stage was switchable from triode to pentode operation to further the flexibility of the output stage. This all posed some interesting challenges for transformer impedance and power ratings.
There is the option of selecting either tube rectifier or silicon diode for the high voltage, the tube is saggy and compressed, the diode is stiff and punchy.
All components were of high quality, ceramic tube sockets, CTS pots, Sprague capacitors for filter and interstage, and the whole design was on tag board.
My aim was for every component to sit parallel to each other and nothing strung between tags, its just a neatness thing, no bearing on reliability or tone.
Speakers and reverb tank were also chosen to replace what this amp came with.
It is a 2 X 10" combo format.
